Özet
In this study, it was aimed to obtain carbon and graphene quantum dot structures from St. John's Wort (Hypericum perforatum L.) flowers, originating from the city of Hatay. Hypericum perforatum L. flower sample was subjected to carbonization at different temperatures such as 200, 225 and 250 ℃ for the desired quantum dot structure yields. It has been observed that the best radiation after carbonization is at 250 ℃. Fourier transform infrared spectrometer, X-ray diffraction and scanning electron microscopy techniques were used to determine the structural characterizations and surface morphology, respectively. The UV radiation of Hypericum perforatum L. flower-based carbon and graphene quantum structures was followed at 365 nm and the blue glow was observed very clearly. With this study, quantum and graphene dot structures based on Hypericum perforatum L. flower have been introduced to the literature for the first time. In addition, the quantum dot structures with blue radiation obtained within the scope of the study will be an alternative reference for many bioimaging and drug delivery system studies.
